Logic Masters Deutschland e.V.

Normal Sudoku rules apply. Additionally:

1. In each box X, if X is odd, then X in that box must appear in row X, column X, or both if possible.

2. In each box X, if X is even, then X and X - 3 in that box cannot appear in row X or column X.

3. 3 of the boxes in the grid, to be deduced by the solver, are cloned magic squares in which each row, column, and diagonal sums to the same number and all digits appear in the same locations in each box.

4. Standard anti-king: cells that are a king's move (in chess) apart cannot contain the same digit.
